Currently i'm using a script for a form on a site, but the problem with it is that when the client receives the form, he wants to be able to simply hit the "REPLY" button and respond to the sender immediately, but when he tries to do this the address located in the "TO" folder is his own and not that of the person sending the form as it usually is....do you know of a script that can do this?

There's a whole bunch of form processing programs -- some have the email of the person sending the message in the FROM field (which would translate to "TO" when hitting reply). You may wish to demo some of the programs listed at http://www.perlarchive.com/guide/Form_Processing

This assumes that your form input is in a hash named %FORM and that your visitor's email address field is named email. You may need to change this to make it work on your program. This simple change will allow you to hit REPLY after receiving the message, and the REPLY-TO email address will be the address of the person who submitted the form.

If the above confuses you, it may be easier to post the emailing portion of your program here so we can help more.
